India were assured of four medals at the Ulaanbaatar Cup in Mongolia after four boxers from the country, including world and Asian silver-winner Sonia Lather (57kg), advanced to the semi-finals yesterday.

Joining her in the last-four stage were Lovlina Borgohain (69kg), Himanshu Sharma (49kg) and Ashish (64kg). All the four boxers are guaranteed of at least a bronze medal each. However, world silver-medallist Sarjubala Devi (51kg) bowed out in the quarterfinal stage after losing a close bout to Mongolian Myagmardulam Nandinsetseg 1-4.
